e is a carrier arm or bar or yoke disposed, in the form shown, in horizontal position, be ing clamped between the two leaves or members of a sleeve or split ring clamp fformed as an extension of a thimble which is permanently mounted upon the outer end of a supporting arm g, the inner end of which latter is secured to a traveler formedas a split ring clamp h which encircles and may be if desired clamped in any desired position of vertical adjustment upon the supporting mast.

The projecting lips of the traveler h are adapted to be drawn together by a screw 7; provided with a handle consisting of a forwardly extending bar provided at its outer end with an operating member. 7

The projecting lips of the sleeve or split ring clampf which encircles the carrier arm, are adapted to be drawn together by means of a screw having a suitable operating handle.

One end of the'arm e is provided with a fender bar Z, the free extremity of which bears against the adjacent surface in which the rivets are inserted.

The threaded inner or rear end of said fender bar passes through an opening in said arm, and is equipped with nuts 0%, which bear against the respective sides of the arm, by

the adjustment of which nuts the fender bar may be set in any desired position of longitudinal adjustment.

The other end of the carrier arm (2 is provided, preferably through an intermediate cylindrical extension, whereof hereinafter,

with a recessed head plate n face to face against which is secured by suitable bolts, a head plate 0 having a corresponding recess.

The combined recesses of the head plates form a spherical socket.

p is the riveting machine, of any preferred construction and arrangement, the blows of the rapidly reciprocated hammer of which (not shown) are employed to beat down the rivets operated upon. It is shown as provided with a clamp plate q (Figure rigidly secured to it, which plate is provided with a vertically disposed open topped tubular extension as shown in said figure.

r is a suspension link, the lower cylindrical end of which is entered and secured in said tubular extension, and the upper spherical between the riveting machine and the yoke,

and said riveting machine may, therefore, be given any desired inclination with reference to a rivet in the vicinity of which it is brought and upon which it operates.

The fender bar Z, as will be apparent, supports the carrierarm e and supporting arm g against the strain due to the vibrations of the hammer or other operating instrumentalit-y of the riveting machine.

The supporting mast is preferably made hollow, as shown in the drawings, and provided with counterweights 23 adapted through suitable connections to counterbalance the weight of the carrier arm e and its attachments including the rivetingmachine.

The counterweights, which are shown in dotted lines in Figure l, are strung upon the end portion of a chain or other flexible connection 11., depending within the hollow interior of the supporting mast, the intermediate portion of which connection passes over a sheave 1; supported upon a bracket arm projecting from the hook supporting collar at the upper end of the mast,and the outer end of which connection is in the form of apparatus shown secured to an eye 10 permanently fixed to the supporting arm g.

The counterweights as shown consist of a series of independent spheres or blocks of metal any desired number of which requisite for the purpose may be employed.

In some forms of my apparatus, when the curved lower portion of a hull is being operated upon, I may employ a supporting mast the lower end of which is curved inward to approximate the sectional profile of the vessel, as indicated in dotted lines at the lower portion of Figure 5.

Manifest-1y the series of independent weights will accommodate themselves to any such curvature of the mast.

The operation of myapparatus will be readily understood: The supporting mast may be engaged through its hook upon any suitable ledge of the structureoperated upon, or other point ofsupport, and the lower end if desired made fast as hereinbefore described.

The supporting arm g, the carrier arm 6, and other parts, are moved together in a vertical direction along the mast, the loosened (if not already loose) split ring clamp or traveler 7t sliding freely thereupon until the riveting machine is brought to the desired position.

When said traveler or clamp his not made too tight upon the mast, said clamp, with the arm g, arm e, and all connected parts, have rocking movement or movement of rotation upon or with respect to said mast as an axis, such rocking movement, however, being limited in the apparatus illustrated, by the contact of the riveting machine and fender bar with the structure upon which the apparatus is mounted.

The vertical adjustment of the parts along the mast, as is manifest, the parts being in equilibrium, requires but slight effort on the part of the operator.

When the carrier arm and connected parts have been brought to the position desired, the traveler or split ring clamp it may, if desired, be tightened upon the mast, and the parts thereby securely clamped in such posi tion. The riveting machine being then in front of a rivet may thereupon be operated and the rivetupset. In shifting the riveting machine along a horizontal row of rivets, to operate upon said rivets in succession, the carrier arm is of course shifted through the sleeve or clamp f.

In the especial construction illustrated, the head plate n instead of being directly connected to the carrier arm 6, is provided with a cylindrical rotatable extension or shank a; (see Figure 4) mounted within and in telescopic relation with respect to the adjacent end of the tubular body of the said arm.

The cylindrical extension is for a portion of its length of diminished diameter as shown in said figure.

s is an inwardly projecting stud mounted in the body of the arm and projecting into the space between the opposing shoulders y at the respective ends of said region of diminished diameter.

The distance from one shouldery to the other is approximately equal to the usual distance from one rivet to its neighbor, and in the operation of the apparatus, after one rivet has been operated upon by the riveting machine, the latter may be moved in a horizontal direction toward or away from the arm 6, until in front of the adjacent rivet, the tubular extension 00, of course, moving with the machine and traveling along the bore of said arm e until stopped by the contact of one of its shoulders y with the stud s.

The second rivet may thereupon be operated upon without other adjustment of the parts than that just mentioned.

In the further operation of the machine successively upon the rivets of such a horizontal row as is shown in Figure 5, after the two rivets referred to have been operated upon, the split ring clamp fis loosened, if not already sufficiently loose, and the arm e bodily shifted along to carry the riveting machine into proximity to one of two adjacent rivets, and said split ring clampf may thereupon be tightened if desired.

The longitudinal adjustment of the arm 6 may be continued until all the rivets in the horizontal row within the reach of said arm have been operated upon.

Thereupon the arm 6 may be elevated or lowered to the next adjacent horizontal row of rivets, or the mast with all its attached parts may be bodily shifted to the right or left.

The entire weight of the arm 6 and machine being counterbalanced by the weights 2?, the operator in the working of the machine, does not support the weight of the latter, and the movements of the machine from rivet to rivet or from row to row are effected with the minimum of efiort.

As will be manifest, all of the rivets within a large area may be operated upon without further adjustment of the parts than the horizontal movement of the arm 6 through the split ring clamp f, and the adjustment of the supporting arm, arm 6, and attachments, upon the supporting mast.

When all the rivets within the area operated upon have been upset, the nut on the screw 01 may be taken off, the screw removed from the opening through which it extends and the supporting mast very quickly and readily shifted along to carry the apparatus into operative relation with another area in which rivets to be upset are situated.

Having thus described my invention, I claim 1. In a riveting apparatus, in combination, a vertically disposed mast adapted to be movably engaged with the upper edge of the vessel, means for removably attaching the lower end of said mast to the side of a vessel or kindred structure, a traveler mounted on said mast and adapted for longitudinal and rotative movement with respect to the same, a carrier arm extending transversely of said mast and engaged in a support formed or connected with said traveler and adapted for movement in the direction of its axis through said support, a riveting machine, and a flexible connection through which said machine is connected to said arm, substantially as set forth.

2. In a riveting apparatus, in combination, a supporting mast, means for detachably connecting said mast to the structure upon which the riveting machine is to operate, a carrier arm connected to said mast and adapted to have movement longitudinally of said mast and also to have movement longitudinally of its own axis, an extension piece engaged with said carrier arm and adapted to have limited movement in the direction of the axis of said arm but independently of said arm, and also to have rotation with respect to said arm, a riveting machine, and a flexible connection between said riveting machine and said extension, substantially as set forth.

3. In a riveting apparatus, in combination, a supporting mast, a horizontally extending carrier arm or yoke free for vertical adjustment with respect to said mast, a cylindrical machine-carrying extension mounted in telescopic relation with respect to said arm or yoke, shoulders formed on one of said devices and a projection extending from the other and adapted to encounter said shoulders, substantially as set forth.

In testimony that I claim the foregoing as my invention I have hereunto signed my name this 10th day of January, A. D. 1900.
